4747 Drone Propeller Glass Fiber Nylon Electric Grey CCW 2Pc

Gemfan 4747 Electric Speed Propeller – Clear Grey (2 Pieces)

Product Description

The Gemfan 4747 is a precision-engineered "square" pitch propeller (4.75-inch diameter and 4.75-inch pitch) specifically designed for high-speed fixed-wing aircraft and small, high-RPM UAVs. Constructed from high-tenacity nylon, this propeller is built to maintain its aerodynamic profile and pitch integrity even under the extreme rotational speeds generated by 1805 to 1806 series brushless motors. The aggressive 1:1 diameter-to-pitch ratio makes it an ideal choice for pylon racing and speed wings, providing exceptional top-end velocity and rapid throttle response. Each propeller is factory-balanced to eliminate vibration, ensuring a stable flight path and reducing mechanical wear on your motor bearings.

Key Features

• Electric Speed Optimized: Tailored for high-velocity fixed-wing applications that require maximum pitch efficiency and high-speed stability.

• High-Rigidity Nylon: Durable construction provides the stiffness necessary to prevent blade "flutter" or deformation during high-RPM operation.

• Balanced Thrust Profile: The 4.75x4.75 geometry delivers a powerful forward "bite," translating motor torque into consistent airspeed and rapid acceleration.

• Universal Adapter System: Includes a comprehensive 6-hole adapter kit (3mm, 3.17mm, 4mm, 5mm, 6mm, and 8mm) to ensure a perfect fit on various motor shaft sizes.

• Low-Vibration Performance: Precision-molded blades reduce harmonic resonance, resulting in a quieter acoustic profile and smoother handling.

• Professional Clear Grey Finish: Offers a sleek, modern look while maintaining excellent resistance to environmental wear and heat.
